Inside the Boiler Room: Would Elena Kagan recuse herself?

From NBC's Political UnitSen. Orrin Hatch (R-UT), a member of the Senate Judiciary Committee, said he thought Elena Kagan should recuse herself from any health-care ruling, since she was the Solicitor General for this administration. The Solicitor General argues the government's cases before the Supreme Court.

So would she? NBC's Pete Williams stops by the Boiler Room to provide some context. And what would happen in a 4-4 tie on the Supreme Court?

Thanks to Beverly in Chicago for the question about Justice Sotomayor and if she'll recuse herself. (Pete answers that one, too).
